ROCKLAND, Maine (AP) — An attorney in Maine says the process of untangling the late Robert Indiana’s assets and transforming his home into a museum likely will be delayed because of a lawsuit.

The lawsuit accusing several people of taking advantage of Indiana before his death must be sorted out before the estate can proceed with plans for a museum showing his artwork. It may take at least two years.

On Wednesday, attorneys for the pop artist known for his “LOVE” series questioned those close to Indiana about his assets, now valued at $60 million.

Estate attorney James Brannan said it would take $10 million to overhaul Indiana’s home and display his artwork.

The reclusive artist died at age 89 on May 19 at his home on Vinalhaven Island, 15 miles (24 kilometers) off the coast.
